Shares of Circle Internet Group slid 5.5% to $106.74 after a widely circulated strong sell rating published on May 29 argued the stablecoin giant is fundamentally overvalued and dangerously tethered to one income stream. The report pegged Circle at 37x EV/EBITDA, calling it overvalued, and noted that 96% of revenue comes from reserve income earned on the U.S. Treasury securities backing its USDC stablecoin. Broader crypto weakness in Bitcoin and Ethereum compounded the selling pressure on a stock already down roughly 64% from its 52-week high of $299.

  • Nearly All of Circle's Revenue Disappears If Rates Fall — In Q1 2026, Circle earned $653 million in reserve income, but the reserve return rate dropped to 3.5%, a 66-basis-point decline year over year as short-term rates eased. That means every Federal Reserve rate cut directly shrinks Circle's top line. The sell report warned that despite adjusted EBITDA growing 24% year over year, future downside looms if Treasury yields decline from current highs. For shareholders, this is like owning a bank that can't make loans — its profit swings with forces entirely outside its control.

  • Growth Is Real but Margins Are Thinning — Q1 2026 EPS fell to $0.23 from $1.11 a year ago, and profit margins compressed to 8% from 11%, even as revenue rose 20% to $694 million.

Distribution costs climbed 17% and operating expenses surged 76%, driven by post-IPO stock compensation. Revenue is growing, but less of it reaches shareholders.

  • New Competitors Are Circling the Stablecoin Market — SoFi launched SoFiUSD on May 27, becoming the first U.S. national bank to offer a stablecoin directly to retail customers, instantly reaching nearly 15 million members.

Circle and Tether still dominate the roughly $300 billion stablecoin market, but bank-issued tokens backed by FDIC-insured institutions could erode Circle's institutional pitch over time.

  • The Bull Case Rests on Products That Don't Yet Generate Meaningful Revenue — Circle is building fee-based products like its payments network and blockchain infrastructure, but non-interest revenues remain tiny compared to reserve income.

Its ARC token presale raised $222 million, signaling ambition, but the consensus among 25 analysts is still a Buy rating with a $145.80 average target — a bet that diversification arrives before rate cuts do. Whether that timeline holds is now the central question for anyone owning the stock.
